Advice from someone who has been around the off road scene for a while
Dont spend money on Kore parts, they are very nice but shock towers are too short to get the most travel out of the front and you cant get bushings the arms anymore, I know many people who had to get real creative or scrap their Kore parts. Also if you are serious about off road performance just go with long arms, they perform so much better then short arms.
Good luck on the wheels though unless you run glass -17 offset is not great on these trucks and you will the rear of the front fender real bad with 37's or larger. Patton Fab can make a great bumper for you if you cant find the DRC one.
Dodge Trucks Xtreme would be a better fourm / FB page to look for these parts.
